Not that I do it, but what is the problem with it then? On the plus side, where the earths are twisted at the point where they leave the cable sheathing they have no chance of separating. I guess the negative side is that it's a pain when it comes to testing as its a chore to un twist them. The only downside I can see is that it's more work for someone when fault finding.

its a chore to un twist them.

That's the whole point Mossep, plus the fact that they can break off if they've been twisted tightly together. So much less bother if you can remove them from the terminal, do the test and then put them back,

Being a chore to un twist them doesnt make it a bad habbit though, it just make sit diffucult lazy sparks like us!. If anything, its a more robust and sound way of terminating them.

Ive never had or seen one snap because of twisting either, I can only imagine it snapping if the cable has been damaged somehow whist stripping it from the T+E, in which case, its better that it snaps whilst wiring it up, than gets terminated and breaks at a later date.

Just for the record I sleeve them individually with a nice bit of 2mm sleeving and fold them over at the end.

What is so bad about doing that then OMS? I know it is frowned upon by some people but never understood why. The only reason that I can think of is that it could stretch the cpc making it thinner but i can't really see that happening from the soft pvc sheath?

Well, just to be controversial, this is I think the most robust reliable way of terminating the cpc's to a socket with twin and earth cable..........

The most common fault I find is an open circuit or higher than expected reading on the cpc's of ring mains. Either a core snapped off, or both cores in one bit of sleeving and one doesn't get terminated and disappears up the sleeving. The latter giving a higher reading than expected.

Twist cores together for about 3 inches, or 77mm. Do not twist the ends, terminate them as separate cores. Stops all slipping up sleeving and gives perfect readings
